The fact that Trump has non-white support does not mean he is not racist. It was because he was racist he was accused of racism in housing back in the day. He was also racist, when he called Mexican immigrants, rapists and criminals. He was racist, when he wanted to set up Muslim registries. He was racist, when he called African countries shit hole nations. He was racist when he said there were very good people on both sides, in reference to the Nazis at Charlottesville. Need I go on?
Some non-white people can also be racist and many of the Trump supporting ones are. Thankfully a tiny minority. Are you saying only white people can be racist?
Also, referring to me as a person of colour when you can refer to my name, is racist. So that makes you a racist, who supports Trump. Which again proves my earlier point that Trump, his followers and his ideology are all racist.
